1 Claim.

This invention relates to seat or chair springs and particularly to the type of resilient seat supporting means that utilizes flat springs made of coiled strips of metal.

The primary object of this invention is to construct a resilient seat support that will not buckle, bulge or get out of shape.

Another object is to provide a chair with a resilient base suitable for supporting the seat frame, which frame may consist of the cushion,

back, sides and arms, independent of the chair legs.

A further object is to provide a spring seat that is simple to construct, economical to manufacture and yet strong and durable.

A'still further object is to provide such seat with springs of variable tension which will satisfactorily accomodate persons of decidedly different Weights.

A fuller understanding of these and other obiects and features-of the invention will be had by referring to the following specifications taken in connection with the accompanying drawing in which like parts are designated by like reference characters and in which:

Figure 1 is a perspective view of a chair having springs of this invention;

Figure 2 is a side sectional view of an outer spring taken along the lines 2-2 of the Figure 4;

Figure 3 is a side sectional view of an inner spring taken along the lines 33 of the Figure 4;

and

Figure 4 is a plan view partly in section taken along the lines 44 of the Figure 2.

A chair embodying the instant invention consists of essentially two parts, the base which supports the coiled spring portions and the chair structure or seat member which resiliently rests upon the coiled portions.

In the drawing the base consists of a rectangular frame I! mounted on suitable legs l2. Extending laterally across the frame II are two parallel supports I3 and Id, of which the front support I3 is slightly lower than the rear support 45 I4, and mounted on the supports I3 and M are a plurality of springs I5.

The springs I5 are made of flat strips of spring steel and have downwardly and inwardly coiled r spiraled ends l6 and I1. The front spirals I6 are slightly larger than the rear spirals I1 and are, therefore, a littlemore resilient.

The springs l5 are mounted longitudinally parallel to each other and rigidly on the lateral supports l3 and I4 at the bottom arcs of their spirals I6 and I1, and are tightly held in a vertical position by clamp-bars I8 and I9.

The clamp-bars I8 and I9 extend laterally through the spirals I6 and I1 and are parallel to and contiguous to the parallel supports l3 and I4 5 respectively. Simple nuts and bolts 2| and 22 projecting through the supports I3 and M, between the springs I5 and through the clamp-bars l8 and I9, are suitable for this assembly. The supports and the clamp-bars can very well be made of stamped metal, wood, or other suitable M material.

Similarly, the tops of the spirals IB and I! are attached together by the upper front and back supports I311 and Ma respectively, and the upper front and back clamp-bars Isa and I9a respectively.

In order todeadensound, and to facilitate and ease the operation of the springs I5, an insulating material 23 is inserted between the leaves of the spring and between the contiguous supports, and clamp-bars. The insulating material 23 may be made of textile fabric, leather or rubber.

The two side springs I5a and I5?) are made to include or to be supplemented by small buffer springs 26 and 21 respectively, to provide for comfortable use by persons of more than average weight. The buffer springs 26 and 21 are shaped somewhat like the Figure 6 and are fastened W within the spirals I6 and I1 by the same supports, clamp-bars and insulating material.

In normal use a person of average weight will: depress the springs I5, I5a and I51) and their respective spirals I6 and I! about two inches or until the upper clamp-bars Mia and I9a almost touch the top of the inside loops 28 of the buffer springs 26 and 21. If a person of heavier weight uses the chair having these springs, the extra weight will be absorbed by the auxiliary spring action of the inside loop portions 28.

Extending laterally and outwardly beyond the side of the springs I5a and I5!) and attached to the upper supports I30! and Ma are round pegs or pins 24 on which there rests or rides the chair structure sides 3|. The sides 3| have small holes 25 for accommodating the pins 24 and are attached together and prevented from spreading or coming off of the pins 24 by the lateral braces35.

The chair sides (it support the back 32, arms 33, cushions 34 and all upholstery and coverings and are supported solely by the two upper supports I3a and Ma and their respective four pins 24. The rectangular structure formed by the sides 3| and braces is slightly larger than the frame H, does not touch it at any point and also does not touch the floor, with the result that the seat portion, and the back and arm members are caused to float or rest on the springs alone.

While the invention is described herein in its preferred form, and while specific terms and language have been used, it is to be understood that the present disclosure is illustrative rather than restrictive and that no limitations uponthe invention are intended other than those which are imposed thereon by the scope of the appended claim.

I claim:

In a chair, a resilient support, comprising in combination, a horizontal base member; a

plurality of co-extensive longitudinal bowed fiat springs having large front downwardly extending spiraled spring ends; a first pair of lower co-' acting clamp-bars and support members extending laterally across the coiled ends joining the springs to the said base; and a second pair of upper co-acting clamp-bars and support members extending laterally across the said springs, the said upper support members having projecting mounting pins.
